SUPPORT FOR MOVING STOCKRODS.

Application led September 7, 1915.

To all whom it may concern.'

Be it known that I, LATHAM H. BRIGHT- MAN, a citizen of the UnitedStates, residing at Columbus, in the county of Franklin and State ofOhio, have invented certain new and useful Improvements in Supports forMoving Stock-Rods, of which the following is a specification.

My invention relates to the improvement of stock supports for nut makingmachines, and the objects of my invention are to provide improvedsupports for the stock or rod while the same is being fed into a machinewhich converts the stock into nuts; to so construct my improvedsupportsas to prevent injury to the spool shaped bearings' thereof through thevibratory movement of the end of the stock rod when the latter isreleased from the spool.

Other objects of my invention will become more apparent after a furtherdetailed description of the accompanying sheet of drawings, in whichsimilar characters of reference designate corresponding parts, and inwhich:

Figure 1 is a view in elevation of two of my improved supports showingthe end stock rod passing through one of said supports and with its rearend portion adjacent to the discharge end of the other support, Fig. 2is an enlarged elevation of one of the supporting heads, and, Fig. 3 isa central vertical section of the same.

At desirable intervals and in proper alinement with each other, Iprovide upright standards or supporting rods 1, these standards beingarranged on a line with the feeding mechanism of any suitable type ofnut making machine. Upon the upper end portion of each of thesestandards 1 is mounted a supporting head, which comprises an uprightsocketed portion or shank 2 which is surmounted by a head 3, the latterbeing bifurcated or of yoke form as indicated in the drawing. The upperend portions of the standards 1 enter the hollow or socket portions ofthe members 2 and are adjustably held therein through the medium ofsuitable set screws 4t which pass through the bases of the members 2.Fixed in a suitably rounded recess in the crotch of the bifurcated head3 vof each of said supports, is a semi-tubular bearing plate 5. Withinthe U-shaped space which is thus formed between the upwardly extendingopposing Specification of Letters Patent.

walls of the member 3 and resting upon the bearing plate 5 of each ofthe supports is the central or barrel portion of -a spool 6, the latter'having flanged spool heads 6, Each of these spools s of somewhat greaterlength than the length of the bearing or the head 3 so that when one ofthe spool end flanges is against one end of the head, the other projectsbeyond said head, this being shown more clearly in Fig. 1 of thedrawing. 'Ihe spool body is prevented from escaping from its seat withinthe bifurcation or head yoke by the insertion of a suitable pin 7through opposing openings 7*L in the side walls of the head 3 above thespool.

In practice, the stock rod from which the nuts are to be formed andwhich is indicated at 8, passes through correspondingly shaped openings6b in the spools 6, said spools thus supporting the stock. Although theopening shown in the spool in Fig. 3 of the drawing, is of hexagonalform in cross section, it is obvious that any suitable shape of openingmay be employed to correspond with the form of the stock in crosssection.

It will be understood that the rod or stock 8 is fed intermittentlythrough the spools to the nut making machine by the usual or a suitablemechanism and experience has shown that where the stock bearing member,which in the present case is in the form of a spool, is of substantiallythe same length as` and held against longitudinal movement in the head3, the end of the stock rod immediately after it leaves one of thespools is, owing to the length of the rod or that portion thereof whichis suspended from the next forward head, subjected to an upward anddownward vibrating movement, with the result that during a limited time,the .end of the stock rod strikes or scrapes the adjacent end of thespool and particularly the edges at the mouth of the opening in thespool, thereby damaging the end edges of the spool opening. In order toovercome this diiiiculty, I have provided the bearing spools 6, asdescribed, of greater length than the length of the heads which supportsaid spools. As the stock rod and the spool rotate together, it will beunderstood that the feeding action of the rod through the spool will byfrictional engagement with said spool, tend to draw the latter to itslimit in the direction of the feed,

2O Y. JJhe combination with a supporting head, of

I this position of the spool being indicated at the right in-Fig. l ofthe drawing. At the -rst vibratory movement of the end of the stock rodafter it leaves the spool end, it is o obvious that any contact Voijtherod and spool will serve to immediately drive said spool back until theadjacent flange 6a is against the end of theY head 3, said spool beingthus moved out of the. Wayof the vi- 1o brating end of the rod and savedfrom dam- Y aging Contact therewith.

`lllthough I have described my improvement as being Vadapted or use 1nconnection with nut making machinery, 1t 1s obviousV that the stocksupporting means a stock supporting member slidably and rotatablymounted in said head, said sup- Gopes of this patent may be obtained forporting member being of greater length than Said head.

2. In a support for a moving stock rod, the combination with asupporting head, of a spool shaped stock supporting member slidably androtatably mounted in said head, said supporting member being of greaterlength than said head.

3. In a support for a moving stock rod, the combination with a standardhaving a bifurcated supporting head, of a stock supporting memberslidably and rotatably mounted in said bifurcation, said member being ofgreater length than said head, and an opening through said stocksupporting member corresponding in shape to the stock to be fedtherethrough.

In testimony whereof I aiIiX my signature in presence of two witnesses.
